OPERATION INSTRUCTIONS
Rhino 172 rotary mowers are manufactured with quality material by skilled workers. These mowers are
designed to cut grass, weeds, small brush and other vegetative material up to 1-1/2” diameter in areas such as
pastures, industrial areas, and roadsides. The mower is equipped with protective deflectors and/or chain
guards to prevent objects being thrown from the mower by the blades, however, no shielding is 100% effective.
All shields, guards, deflectors, and chains equipped on the unit must be maintained on the mower in good
operational condition.
It is the operator’s responsibility to be knowledgeable of all potential operating hazards and to take every reasonable pre-
caution to ensure oneself, others, animals, and property are not injured or damaged by the mower, tractor, or a thrown
object. Do not operate the mower if passersby, pets, livestock, or property are within 300 feet of the unit unless:
• All THROWN OBJECT SHIELDING including, Front and Rear Deflectors, Chains Guards, Steel Guards,
